(TheNewswire)

Toronto, Ontario November 25, 2025 TheNewswire – Laurion Mineral Exploration Inc. (TSX.V: LME | OTC: LMEFF) (‘LAURION’ or the ‘Corporation’) is pleased to announce encouraging results from its 7,700-metre Summer 2025 drill exploration program at the 100%-owned Ishkõday Project, located 220 km northeast of Thunder Bay in Greenstone, Ontario. The first five drill results were announced in the Corporation’s press releases dated August 19, 2025 and September 23, 2025, respectively, which targeted the high-grade gold-bearing vein systems of the Sturgeon River Mine area. Reference is also made to the Corporation’s press releases dated September 5, 2025, May 27, 2025 and May 8, 2025.

The reported drill holes below, LME25-063, LME25-064, LME25-065 and LME25-066, total 1,806 m. The holes were designed to evaluate the northeast extension of the mineralized system at the historic Brenbar Mine, with hole LME25-063, and then stepping out to the northeast of the Brenbar historic mine shaft targeting the untested M50 Quartz vein series with further drill holes.

Highlights of Drill Holes LME25-063, LME25-065 and LME25-066

• LME25-063        0.7 m @ 2.67 g/t Au from 139.50 m to 140.20 m;

• LME25-063        0.5 m @ 1.26 g/t Au from 393.40 m to 393.90 m;

• LME25-065        0.50 m @ 1.78 g/t Au from 91.10 m to 91.60 m;

• LME25-065        1.80 m @ 0.95 g/t Au from 149.60 m to 151.40 m, including: 0.80 m @ 1.90 g/t Au from 150.60 m to 151.40 m;

• LME25-065        0.50 m @ 1.32 g/t Au from 292,30 m to 292.80 m;

• LME25-066        1.50 m @ 1.02 g/t Au from 272,50 m to 274.00 m; and

• LME25-066        0.70 m @ 2.42 g/t Au and 1.90 Au/t from 389.0 m to 389.70 m.

‘ While these results represent the early stages of testing in a geologically complex corridor, their significance lies in extending our knowledge of mineralization continuity between the historic Brenbar and Sturgeon River Mine areas, ‘ stated Cynthia Le Sueur-Aquin, President and CEO of LAURION. ‘This is the first time drilling has been completed across this untested structural corridor, and it is yielding valuable geological insight with oriented core, that will guide the next phase of our exploration program. Our focus remains on defining the broader mineralized system that links multiple historic mine zones, ultimately positioning Ishkōday as a district-scale gold and base metal opportunity.’

Table of Assays for Drill Holes for LME25-063 to LME25-066

Note: (Intervals represent core length. The interval widths reported are down-hole widths. The true widths of the mineralized zones are not known at this time as there is insufficient information to determine the orientation of the mineralization. True widths are estimated at ~70–90% of reported intervals.)

Sampling and QA/QC Protocols

All drill core is transported and stored inside the core facility located at the Ishkõday Project in Greenstone, Ontario. LAURION employs an industry standard system of external standards, blanks and duplicates for all of its sampling, in addition to the QA/QC protocol employed by the laboratory. After logging, core samples were identified and then cut in half along core axis in the same building and then zip tied individually in plastic sample bags with a bar code. Approximately five or six of these individual bags were then stacked into a ‘rice’ white material bag and stored on a skid for final shipment to the laboratory.

All core samples were shipped to the ALS facility in Thunder Bay, Ontario, which were then prepared by ALS Global Geochemistry in Thunder Bay and analyzed by ALS Global Analytical Lab in North Vancouver, British Columbia. Samples are processed by 4-acid digestion and analyzed by fire assay on 50 g pulps and ICP-AES (InductivelyCoupledPlasma – AtomicElement-Spectroscopy). Over limit analyses are reprocessed with gravimetric finish.

A total of 5% blanks and 5% standard are inserted randomly within all samples. 5% of the best assay result pulps were sent for re-assays. All QAQC were verified, and no contamination or bias have been observed. The remaining half of the core, as well as the unsampled core, is stored in temporary core racks at the core logging facility in Beardmore and moved to the core storage facility at the Ishkõday Project.

Glenstar Minerals Inc. (CSE: GSTR) (OTCQB: GSTRF) (FSE: VO20) (‘Glenstar’ or the ‘Company’) announces that it has granted a permit by the Bureau of Land Management (the ‘BLM’) to conduct the Phase 2 drill program at its Green Monster Project in southwestern Nevada.

The permit allows the Company to drill nine (9) holes over four (4) locations on the property and will be comprised of approximately 300 metres of strike length exploration. As currently planned, Glenstar will collar two (2) holes in the area of the primary drilling undertaken in the Phase 1 drill program; three (3) holes will focus on the area that is considered the ‘discovery’ zone 150 metres to the west of the primary Phase 1 drill site, and two (2) holes each at two (2) sites will be situated further west along what is believed to be the mineralized east-west trending belt.

The precise location of each drill hole is yet to be determined and will be decided upon review of the data gleaned from the previously announced Hybrid-Source Audio-Magnetotellurics Survey (the ‘HSAMT‘ or ‘Survey‘) that was conducted by Hasbrouck Geophysics, Inc. (‘Hasbrouck‘) of Prescott, Arizona and Advantage Geophysics, Inc. (‘Advantage‘) of Phoenix Arizona. This survey has now concluded and the results, along with the various data sets, will be contained in a final report that will be provided to the Company by Hasbrouck. This report is expected to be completed in early December and the results will be instrumental in determining the best, and most advantageous, location for each hole of the Phase 2 drill program.

The survey data was acquired at intervals of 50 metres along 13 lines and was conducted by a 3-person field team from Advantage, in conjunction with Hasbrouck. The data collected is currently being analysed and interpreted using sophisticated software that will convert it into two- and three-dimensional cross-sections in depth and/or elevation formats. The complete data set will be interpolated into a rectangular cube and horizonal depth slices, referenced to the surface. The final report will detail the methodology, data acquisition, processing, modeling, and interpretation of the data (see news release dated October 29, 2025) and will provide Glenstar’s geologic team with the information it needs to best determine the location of each drill hole in the Phase 2 program.

Glenstar CEO, Dave Ryan, stated, ‘The completion of the geophysical field work is an important milestone. Once we have the final report from Hasbrouck we will use this data to target sulfide facies mineralization in the area of the oxide mineralization that was intersected last summer.’

Project Background & Recent Exploration Work

The Green Monster Property is comprised of 35 federal lode claims covering ~700 acres located in Clark County, Nevada, on the west trending spur of the Spring Mountains and is approximately 40 miles southwest of Las Vegas. Until the recent drill program in May of 2025, no drilling was ever conducted on the property, but the Company’s previous identification of robust nickel-copper with anomalous cobalt from sampling work done in 2022 indicated that several targets were ideal for shallow RC drilling (see news releases dated May 28, 2025, and July 16, 2025).

Glenstar acquired the Green Monster Property and conducted initial groundwork in 2022 that included reconnaissance geologic mapping, surface rock sampling, soil sampling, and a drone magnetic survey. Channel sampling across the exposed back of a raise off the main shaft returned 1.18 meters of 3.77% Cu (Copper), 3.06% Ni (Nickel), 0.21% Co (Cobalt) and 6.83% Zn (Zinc). These values are well in excess of select dump samples from historical underground workings and represent in-place, vein style mineralization. Sampling of oxide and sulfide bearing boulders directly downhill of the patented workings has confirmed the presence of very high zinc (>10%) and silver (>200ppm), as well as copper, uranium, and lead. (Sampling results provided above were previously published in the Green Monster Project NI 43-101 Technical Report dated June 20, 2023, Section 7.5).
